  • Patent number: 8763942
    Abstract: A grinder for a coffee machine includes a first grinding disc disposed in a housing. A drive moves the first grinding disc about a rotational axis. A second grinding disc is disposed in the housing. There is a threaded part in which the second grinding disc is attached. The threaded part is screwable into the housing. A drive wheel is disposed coaxially with respect to the threaded part and rotates the threaded part with respect to the housing. A grinding gap between the two grinding discs is thereby able to be set. A setting wheel co-operates with the drive wheel, the setting wheel being attached to the housing. A supply opening is disposed in the housing for supply of coffee beans to be ground. A path guide opening guides away the coffee ground between the two grinding discs. A holder is adjustably attached to the housing and is fixable in any position.

  • Publication number: 20120138721
    Abstract: Inserted into the housing (2) of a grinder for a coffee machine is a first grinding disc (6), which, via drive means (3), is drivable about a rotational axis. A second grinding disc (9) is attached in a screw-in part (7) which is screwable into the housing and is rotatable with respect to the housing (2) by adjusting means (15), (16). By rotating the screw-in part, the grinding gap between the two grinding discs (6), (9) can be set. The adjusting means comprise a setting wheel (16) arranged on a holder (17) which is attached to the housing (2) and which can be adjusted and fixed in any position with respect to the housing (2). This setting wheel co-operates with the drive wheel (15) attached to the screw-in part (7). The setting wheel (16) which is attached to the holder (17) can thereby engage in the drive wheel (15) in any desired position with respect to the housing, whereby the thus equipped standard grinder can be inserted into different types of coffee machines.

  • Patent number: 6579456
    Abstract: A device and a method are described, which are used for precipitating beverage sediment from the rinsing mixture of beverage production machines and which comprise a rinsing conduit, a sediment receptacle and a filtering means. In order to design a device of this type in a structurally simple manner such that it can be serviced more easily, it is suggested that the filtering means should comprise a first and a second filter which are arranged one after the other when seen in the direction of flow of the rinsing mixture and which are each provided with filtrate discharge means and that a flow connection for the rinsing mixture discharged from the rinsing conduit and for the filter cake precipitated on the first filter should be provided, said flow connection bypassing said first filter and leading into the sediment receptacle.
